Description:
These parameters present, in Celsius degrees, the heatsink temperature on the U, V and W arms (P0030, P0031
and P0032), of the rectifier (P0033), and also of the internal air (P0034).
They are useful to monitor the temperature on the main inverter sections in case of an occasional inverter
overheating.
